How do you handle the pitch accent when speaking at normal speed?

I've been recording myself daily to fix my pronunciation but I feel like I lose all my pitch accent control the moment I try to speak full sentences. I know the theory behind the acute and circumflex accents in Lithuanian, but keeping them consistent in connected speech feels impossible. Are there any drills or maybe a tool like Chickytutor.com that can provide feedback on my pitch patterns during conversational practice?
